How to properly remove a relay from a Beko refrigerator: instructions with photos and tips

Relay in refrigerator Beko is a small but critical element responsible for starting the compressor and protecting against overloads. If the refrigerator suddenly stops freezing, makes uncharacteristic clicks, or does not turn on at all, the problem may lie in a faulty relay. However, before you run to the service center, you should try to diagnose and replace the part yourself.

In this article we will look in detail at how to remove the relay from refrigerators Beko different series (including popular models CS 333020, GNE 114720 X, RCSK 310M20 S and others), what tools will be needed, and what to pay attention to in order not to damage other components. You will also learn how to distinguish a start-up relay from a thermostat and when it is better to entrust their replacement to professionals.

What relays are installed in Beko refrigerators and where they are located

In refrigerators Beko two types of relays are used, which are often confused with each other:

• 🔧 Start-protective relay —attached directly to the compressor housing (usually on the side or top) and is responsible for starting the motor and protecting it from overheating. Outwardly it looks like a small plastic box with wires.
• 🌡️ Thermostat (thermostat) - is located inside the refrigeration chamber (usually behind a plastic panel or next to the lamp) and regulates the temperature, turning the compressor on/off based on a signal from the sensor.

In most models Beko the starting protection relay is of type DANFOSS 103N0016, ASCO R1-1 or similar, and the thermal relay is of K59-L1438, WDF19 and others. The exact brand can be found by looking at the sticker on the body of the part or in the technical data sheet of the refrigerator.

To find the relay, inspect the compressor (the black metal block at the bottom of the back wall of the refrigerator). The start-up relay is usually attached to it using a spring clip or screws. The thermal relay, in turn, is hidden inside the chamber - you will have to look for it under the decorative panels.

Tools and preparation for dismantling

To remove the relay from the refrigerator Beko you will need:

• 🔨 Phillips and flathead screwdrivers (the size depends on the screws on your model).
• 📸 Phone or camera - to photograph the wiring diagram (this is critical if you are not a master and are doing repairs for the first time).
• 🔌 Multimeter (to check the serviceability of the relay before removing).
• 🧤 Rubber gloves (protection from static electricity and accidental short circuits).
• 📦 Container or bag for screws and small parts (so as not to lose).

Before starting work, be sure to:

1. Disconnect the refrigerator from the mains by removing the plug from the socket.
2. Wait until the compressor has cooled down (if it has been running recently).
3. Free up space around the refrigerator for easy access to the back wall.

If you remove the thermostat, you will additionally have to remove food from the refrigerator compartment and remove shelves or drawers that block access to the panel with the temperature regulator.

⚠️ Attention: Do not touch the relay or compressor contacts with bare hands if the refrigerator was turned on less than 10 minutes ago. Residual voltage may be stored in capacitors!

Step-by-step instructions: how to remove the start-up protection relay

The start-up protection relay is attached to the compressor and usually has 2-3 wires connected to the contacts. Follow these instructions:

1. Take a photo of the location of the wires on the relay and compressor. This will help you connect everything back correctly.
2. Carefully disconnect the wires by pulling on the connectors (do not pull on the wires themselves!). If the contacts are stuck, use a flat screwdriver to pry them off.
3. Loosen the fastening of the relay to the compressor:
   • If the relay is fixed spring clamp —pry it with a screwdriver and remove.
   • If the relay is screwed on screws unscrew them with a Phillips screwdriver.

Remove the relay from the compressor by pulling it up or to the side (depending on the model).

On some models Beko (for example, GNE 124720 X) the relay can be hidden under a protective cover. In this case, first remove the casing by unscrewing 2-3 screws.

What to do if the wires are not disconnected?

If the connectors are “stuck” to the contacts, do not use force - this may damage the wires. Instead:

1. Treat the contacts with alcohol or WD-40.

2. Wait 5-10 minutes.

3. Gently rock the connector from side to side while pulling towards you.

After removing the relay, inspect it for melting, blackening or swelling. If there are such defects, the part definitely needs to be replaced.

How to remove the thermal relay (thermostat) in a Beko refrigerator

The thermal relay is located inside the refrigeration chamber, and its dismantling requires partial disassembly. Algorithm of actions:

1. Unplug the refrigerator and remove all food from the chamber.
2. Remove the top shelf (if it interferes with access to the panel with the temperature controller).
3. Unscrew the screws securing the plastic panel under which the thermostat is hidden (usually 2-4 screws).
4. Carefully remove the panel without damaging the plastic latches.
5. Behind the panel you will see a thermal relay - a small round or rectangular part with a sensor tube and wires.
6. Disconnect the wires (after photographing their location first!) and the sensor tube.
7. Unscrew the screws securing the thermal relay to the housing and remove it.

On models Beko with electronic control (for example, BCS 210), the thermal relay can be integrated into the control board. In this case, replacing it requires soldering or completely replacing the module - it is better to contact service.

⚠️ Attention: The thermal relay sensor tube is filled with freon. Do not bend or damage it - this will lead to a gas leak and incorrect operation of the new relay!

How to check the relay before replacing

Before buying a new relay, make sure that the old one is really faulty. To do this, you will need a multimeter.

Checking the start-up protection relay

Set the multimeter in resistance testing mode (ohmmeter) and follow these steps:

1. Connect the probes to the contacts 3 and 4 (usually they are marked on the relay body). The resistance should be between 20-40 Ohm.
2. Turn the relay over and shake it. If you hear a knocking or rattling sound, a magnet or spring has broken off inside, which indicates a malfunction.
3. Apply voltage 220V to the contacts 1 and 2 (through an incandescent light bulb for safety). A working relay should click and close the contacts 3 and 4.

Checking the thermal relay

For thermal relay:

1. Ring contacts 3 and 4 (common and normally open). At room temperature they should be closed.
2. Immerse the thermal relay sensor in cold water. After 1-2 minutes, the contacts should open (you will hear a click).
3. Take out the sensor and wait until it warms up. The contacts should close again.

If the relay does not pass at least one of the tests, it must be replaced.

Typical mistakes when removing a relay and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to even more serious damage. Here are the most common:

• ⚡ Forgetting to photograph the connection diagram — as a result, the new relay is connected incorrectly, which leads to a short circuit.
• 🔧 They use excessive force when disconnecting wires or removing a relay, breaking plastic latches or contacts.
• 🌡️ They damage the thermal relay sensor tube, which makes the new relay inoperable.
• 🔌 They do not check the new one relay before installation —defects or model incompatibility may go unnoticed.

To avoid problems:

• Use only original spare parts or analogues recommended for your model Beko.
• If the relay is “stuck” to the compressor, do not try to tear it off - treat the contacts with alcohol or a special liquid.
• After installing the new relay, turn on the refrigerator and check its operation for 30 minutes before putting away tools.

When it is better to entrust the replacement of a relay to a specialist

Not all relay failures can be repaired independently. Contact the service center if:

• 🔧 The relay is soldered into the control board (typical for models with an electronic display).
• 🌡️ After replacing the relay, the refrigerator is unstable (for example, the compressor turns on for 5 seconds and turns off).
• ⚡ You have found melted wires or traces of a short circuit on other parts.
• 📉 The refrigerator Beko is under warranty - independent repair will void it.

The cost of replacing a relay in the service varies from 1500 to 3500 rubles (depending on the model and type of relay). However, if the problem lies in the compressor or electronics, the repair price can rise to 8000-12000 rubles.

⚠️ Attention: In some models Beko (for example, with inverter compressors) the relay is integrated into the control system. Replacing it requires flashing the module - this can only be done by a certified technician.

FAQ: Frequently asked questions about relays in Beko refrigerators

Can the relay be repaired or just replaced?

In 90% of cases, the relay cannot be repaired - it has to be replaced. The exception is when the problem is in oxidized contacts (they can be cleaned) or a weakened spring (sometimes it can be bent). However, such measures are temporary.

Which relay company is better to buy for Beko?

Optimal options:

• Original relays Beko (the part number is indicated in the refrigerator passport).
• Analogues from Danfoss (series 103N, 103G).
• Relays ASCO or Start (for start-up protection).
• Thermal relay K59 or WDF (for mechanical thermostats).

Avoid cheap Chinese analogues without markings - they often fail after 1-2 months.

What happens if you connect the relay incorrectly?

The consequences depend on type of error:

• If you mix up the wires, the compressor may not start or work in the opposite direction (which leads to its breakdown).
• If you connect a relay with other characteristics (for example, for a lower current), it will burn out at the first start.
• Incorrect connection of the thermal relay will lead to to constant operation of the compressor or its complete failure.

Always check the connection diagram (it can be found in the instructions for the refrigerator or on a sticker inside the chamber).

How long does it take to replace the relay?

If you are prepared and have all the tools:

• Replacement of the start-up protection relay - 15-30 minutes.
• Replacement of the thermal relay - 30-60 minutes (due to the need to disassemble the camera).

For beginners, the process can take up to 2 hours, especially if difficulties arise with disconnecting the wires.

Where to buy a relay for a Beko refrigerator?

Purchase options:

• Official service centers Beko (warranty on parts, but the price is higher).
• Stores of spare parts for household appliances (for example, 220 Volt, M-Video, Eldorado).
• Online platforms: AliExpress (cheaper, but long wait), Yandex Market, Ozon.
• Markets or refrigerator repair shops (sometimes they sell used parts in good condition).

Check before purchasing refrigerator model and relay number (it is indicated on the body of the old part).
